Player information and local storage
The localStorage key copero.career.v1 contains your chosen name, nationality, position, shirt number, attributes, seed, decisions and season history. The save is not sent to a site-owned server. Use a fictional name and avoid sensitive personal information.
Language and your controls
The selected language is part of the page URL, not a tracking cookie. Changing language on this site uses the same local save. Starting over asks before replacing it. Clearing this site’s browser data deletes the save; changing devices does not transfer it. If storage is blocked, progress may last only in the current tab.
Result images
Downloading a retirement card creates a PNG locally with your browser’s canvas. Nothing is uploaded. A shared image contains the player name, nationality and generated career statistics, so review it before sharing elsewhere.
Analytics, advertising and cookies
Copero uses Google Analytics 4 (G-4JYX8WF2SZ) to understand page visits and site usage. Google may receive page URLs, referrers, browser and device details and approximate location, and may use first-party cookies such as _ga and _ga_4JYX8WF2SZ to distinguish visits and sessions. We do not deliberately send your chosen player name, career save or season history to Analytics. You can block Google Analytics or manage cookies in your browser. Fonts remain local and game saves remain in localStorage. This edition does not include AdSense.
Plausible Analytics
Copero also uses Plausible Analytics for aggregate visit statistics, including visited pages, referring sites, browser and device type, and approximate country. Plausible does not use cookies or access your career save. This does not change the separate Google Analytics cookie use described above. We do not send player names, career saves or season history as custom analytics data.
Hosting requests
Cloudflare is the configured hosting provider. Requests can involve IP addresses, requested URLs, browser information and operational logs. Local gameplay does not prevent ordinary hosting activity. There is no public career database or cloud recovery service. Contact details appear below.
